Implementation Reference

• src/workflowy_mcp/server.py:258-281 (handler)

  MCP tool handler function decorated with @mcp.tool(). Handles rate limiting, calls client.complete_node(), error handling, returns updated node.
  @mcp.tool(name="workflowy_complete_node", description="Mark a WorkFlowy node as completed") async def complete_node(node_id: str) -> WorkFlowyNode: """Mark a WorkFlowy node as completed.

• src/workflowy_mcp/client/api_client.py:180-191 (helper)

  Core client method in WorkFlowyClient that issues POST /nodes/{node_id}/complete HTTP request, handles response/errors, returns WorkFlowyNode.
  async def complete_node(self, node_id: str) -> WorkFlowyNode: """Mark a node as completed.""" try: response = await self.client.post(f"/nodes/{node_id}/complete") data = await self._handle_response(response) # API returns the full node object return WorkFlowyNode(**data) except httpx.TimeoutException as err: raise TimeoutError("complete_node") from err except httpx.NetworkError as e: raise NetworkError(f"Network error: {str(e)}") from e
• src/workflowy_mcp/models/node.py:8-137 (schema)
